My blue C2 964 rebuild thread

PeterS said:
Timing chains look in excellend condition. I'm tempted to replace them anyway. I will wait for pricing. Any thoughts? Obviously its easy to say change them, but where do you draw the line?

From my understanding it's common place to replace chains, ramps and tensioners at this point in an engines life. Although of course if your builder says they're all fine...
 
Ramps (sliders?) and tensioners are all being replaced. Chains he says is "its one of them, they look perfect, but you can never tell"

Tonight I will be ploughing through my huge folder of receipts and service history to see what's been done.

Im pretty sure Ill be changing them, but will wait for his costings and advice.

Just had a thought - if you need cams also... I have a set...

OK, went to see my engine in intensive care.

Its now dis-assembled.

The "noisy tappet" was the bolt that holds one of the rocker shafts in had broken (it had been welded previously too!).

The shaft had worked its way sideways and the rocker started to be at an angle as the shaft had moved. As to whether or not it has caused the rocker shaft casing to be oval or not we cannot tell at this time, until the head is stripped. Fingers crossed.

The angled rocker has damaged the camshaft.

Shims on the end of the camshaft were missing. The cam chain sprocket has marks were it has been moving, and there is a pin that was on its last legs.

It has had one new (or replacement, probably secondhand) barrel in the past. This barrel is in OK condition, but the other 5 have hatching marks and need replacing, so its 6 new (or good used) barrels and pistons.

I need a new (or used) camshaft.

Some of the nuts and washers in the engine are non standard and really bodged. some studs replaced, others not, wrong nuts fitted. It grieves me that someone has done a top end rebuild and not bothered to do it right. I will be going through the receipts for the last 10 years to see who might've done this, but as the car is 21 years old it may have been done a long time ago.

The bearing shells for the oil pump are worn through to the copper, but the indy says these can wear through at about 60,000 miles anyway.

The conrods look in good order, so new bolts, shells, polish crankshaft, and strip down the oil pump to check it but I am told these are normally pretty good so it should be OK.

The good news is that everything is fixable. I have decided against 3.8 barrels and pistons, as because my car was in such poor condition, just making it into a properly built engine will be a dramatic improvement anyway.

Tim-ware is knackered, so will all be replaced. It has been welded, siliconed and had holes cut into it previously.

I will have more idea of costs when everything is priced up.

Thanks to SteveJC I now have a decat pipe to go with the existing G-pipe, and the primary silencer isn't standard either. My indy says he doesn't know what it is, but its a sports pipe of some description.

I reckon I will have to got through all this cars history records and find out what has really happened to it. However its going to have a better quality of life from now on.

Sounds almost as much as my 964 RSR project car and dont ask :eek:

get a solid and reliable 3.6 :thumb:
 
It sounds like a real goon has been there before. Regarding the Cylinder barrels, what is actually wrong with them? Hatching marks are normal but piston scoring is not. Normally they need to be measured to see if they are in spec or not. Your indy should be able to find a good replacement set for £6-800.
 
Peter you have my symapthies. My rebuild will hopefully be quite mundane by comparison.
Its shocking that someone would have treated your engine in that way.
It reinforces the point that word-of-mouth recommendation is so important to help choose who you let loose on your car. It's good to know that forums like this will always steer you in the right direction.
 
The previous owner told me it had extensive service history.

All that He has said is tue, and I have a folder full of stuff.

He spent £,000s on it himself, including a bill for over £2000 from Nine Excellence on 25/5/12 for a service including the tappets.

Looking through the receipts it looks like is the culprit for the shoddy internal work, in 2007 is The Classic & Sports Car Workshop, Cackle Street, Brede.

There is an invoice from them to dismantle to crankcase level and replace seals etc. dated 15/8/07 and the bill was only £1171 inc VAT.

There is also a bill for £3700 from Specialist Cars of Malton in 2011, and whilst a lot of that is external stuff, springs etc, it is also service, rocker gaskets and the like.

So it has been to what we would all expect to be the right places, which just goes to show that most of the owners have been trying to do the right thing with it.

Problem is no matter what the invoice says, unless you actually see the work that has been done youself how can you be certain it isn't bodged?

You're a braver man than me Pete for taking this project on, but the world will be a better place once you've finished putting the old girl right again... :thumb:
 
It looks like the garage has covered themselves as well.

He quite clearly says that within 4 weeks someone needs to check that he has used the right nuts and bolts!
 
I'd be checking the boot to see if they tried to remount the engine there! :bandit:

I would have interpreted that to mean that torques of nuts and bolts should be rechecked within four weeks, i.e., after the engine has been run hot a few times.

That would have been my interpretation, but judging by what has been found I think Pete might be right.

There is no VAT on that so called Invoice. I cant imagine any half decent Garage not being VAT registered, even the cheque is made payable to a person not the business. All very peculiar.
